| The explosion welding is a process that form a strong joint surface between two pieces of metal by the pressure of explosives. Compared with the conventional process, this process the advantage is to be able to welding two different kinds of metal together in large area, and less investment, low cost,is an efficient way to manufacture composite board.In recent years, the demand is higher and higher on the scale of composite board. As surface exposed blasting explosion welding, however, like other blasting engineering, in the process of operation will produce shock waves, noise, vibration, toxic and harmful gases, individual flying rocks, impact explosion field surrounding environment. Currently, there are scholars from a security point of blasting safety evaluation index system is constructed using the analytic hierarchy process, but the blasting environment evaluation index system based on an environmental point of view is still very few scholars involved.From the perspective of environment, This article made a research on the environmental impact evaluation index system of explosion welding field..By large explosion welding field site investigation, expand the study of the environmental impact factors explosive welding job, build a3-level environmental impact of large-scale explosive welding field evaluation index system and fuzzy comprehensive evaluation method did not take measures and take measures after explosive welding field of environmental impact assessment. The results show that, the system can be objective, convenient, fast and fully reflect the environmental impact of the degree of the explosive welding field surrounding ecological environment, vibration, acoustic environment and social environment of the integrated impact, timely understanding of the cause, the right to re-analysis of the environmental impacts from the indicators put forward effective measures to control, to provide a scientific basis for the explosion field site selection and environmental protection. |
